Disclaimer from someone who grew up with the Mad Max trilogy:
Film is first and foremost a visual medium. If you need exposition and elaborate plots in order to enjoy a movie this franchise is not for you. So do yourself a favor and stay the fuck away cause it doesn't need your attention. Mad Max film series was always modeled after the Dollars trilogy. Like the man with no name Max is a man of action and few words and George Miller like Leone, Kubrick and Malick before him has mastered telling a story strictly through the use of visuals.
